I'm in a long term relationship with a girl from my university. I have been since the summer before freshman year. I was completely happy with her at school, but now it's summer. If it helps you guys understand my desirability, i'm at a top school and will be attending medical school in a couple years, and everybody knows it. Plus, i've been seriously lifting for years, so i'm no slouch.

I wanted to hang out with a friend from high school. For our entire relationship we've just been friends and nothing more, but i've always had a crush on her. Anyways, we hang out after not seeing each other for 2 years, and I never tell her about the gf.

At the end of the evening, she comes onto me strongly and I didn't stop it... The instinct to act on my crush took over and we go to second base, luckily not further.

I basically want to know what you guys think. All my bros that I've told are pretty disgusted. I am too. I told the gf, she took it well but it's something she'll always hold against me.

I just wonder, how many crushes have to come onto me while i'm in a ltr before I either give in or regret the missed opportunities? This time it only took one because i've literally liked the other girl for years...

Does anybody have any experience with this or am I alone? Where should I go from here?
